Cenozoic Era

This is the 3rd and current era in the Phanerozoic Eon. It has many changes.

Following the Cretaceous-Paleogene Extinction, which ended all dinosaurs and Ammonites, mammals and birds rose to dominance in the Paleogene and Neogene periods.

Climate was suitable for most of the Cenozoic, until the Quaternary glaciation, which cause an ice age for thousands of years.

In the late Quaternary, the Quatenary, or Holocene Extinction, is an ongoing extinction that has featured many losses and changes in animals and plants, due to human activity.

Humans are the current dominant species since the Quaternary Period.

This era has been deemed the Age of Mammals and Age of Man.
